• 4.2 of the ACS and EAP - TLS with AD and prefix problem

  Hello

  We have the following situation:

  -2 X ACS (ACS SE 4.2 1 x and 1 x 4.2 ACS) for domain

  -2 x ACS (ACS SE 4.2 1 x and 1 x 4.2 ACS) for domain b.

  First of all, there is a problem to have an ACS SE and a CBS work together for an area, I do not? When we haven't had that one area and the two SE ACS were responsible for domain A, it worked.

  Now after the changes, authentication of machine with EAP - TLS is no longer in effect. In the newspapers, it always says that "external user DB is unknown" for a username (machine) as host/abc.domain.ch

  This is the normal output of the Remote Agent, he finds the host but then nothing happens:

  It is clear that the test failed because of the bad 'past to a computer' but it's a different output as before. I saw that in ACS 4.1, you can change the prefix of send_break_action for nothing, but in 4.2 it is no longer possible.

  This could be the problem, or if someone sees no other problem?

• 802. 1 x EAP - TLS for wired users with ACS 5.5

  Hi all

  We are setting up a new configuration for wired users authentication with 802.1 x (EAP - TLS). ACS 5.5 we use as an authentication server.

  We have added the certificate (internal) CA root and certifcate for ACS signed by CA. Now, we want to check that authentication works or not. I hope that the CA root and identity certifcate also we need to install in laptop computers. But I don't know how to download the certifcates for client machine manually to CA.

  Please suggest on how to get certificates for clients both manually and automatically?

  Thank you

  Vijay

  Hi Vijay,

  for Wired 802.1 x (EAP - TLS) you must have the following certificates:

  Intermediate server on ACS - Root CA, CA certificate,

  The customer - Root CA, intermediate CA, user certificate (in the case of user authentication) or Machine certificae (in the case of authentication of the computer)

  I do not know what third-party certificate you use, if its Microsoft in the House or any other certificate server, you need to download the client certificate to the server itself.

  In the case of Microsoft, there will be a user certificate template. You can select and create user certificate

  This is an old document, but a computer certificate for the user configuration steps, you can see the steps to download the certificate user if his server from Microsoft:

  http://www.Cisco.com/c/en/us/support/docs/security/secure-access-control...

  In case you use the third serevr certificate, then you must check with them on how to download the certificate of the user

  See you soon

• [Cisco ACS 5.2] EAP - TLS authentication failure

  What we are e

  Hello

  I set up a WiFi connection on Windows XP and Windows 7 with EAP - TLS (using Cisco WLC 7.0.235.3 and Cisco ACS 5.2.0.26.10). It is configured with the authentication of the computer and computer certificates are automatically registered for Microsoft PKI.

  It works well!

  Now, I configured Windows 8 with the same configuration.

  First authentication works, but if I manually disconnect and reconnect, I got this error on ACS: 22047 username main attribute is missing from the client certificate

  In the EAP packets, we could see that Windows 8 sent a TLS session but ticket session has not properly taken over by ACS...

  Configuration of the ACS, we checked the option "enable EAP - TLS Session resume' with the session timeout"7200 ".

  I found this bug

  http://Tools.Cisco.com/support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId= CSCtn26538& from = summary

  It seems to be my problem but the reboot does not work in my case...

  It is set at 5.3 (0.40.2).

  I plan to install version 5.4.

  Do you know if this fix is supported by 5.4?

  Thanks for your help,

  Patrick

  Hi Patrick,

  What is set in point 5.3 must be set in point 5.4.

  Even if the same issue appeared with 5.4 there an ID different bug and identified as an independent issue (with different causes, usually)

• Authentication EAP - TLS with ACS 5.2

  Hi all

  I have question on EAP - TLS with ACS 5.2.

  If I want to implement the EAP - TLS with Microsoft CA, how authentication computer and user will be held?

  Understand that the cert is required on the client and the server end, but is this certificate to the computer links or links to individual users?

  If the links to the user, and I have a shared PC connection by few users, is that each user account will have their own certificates?

  And each individual user will have to manually get the CA cert? is there another method that my environment has more than 3000 PCs.

  And also if it binds to the user, any user can get their CA cert with their AD username and password, if they bring in their own device and try to get the CA certificate, they will be able to properly install the cert in their device on the right?

  I hope you guys can help with that. Thank you.

  Hope this will answer most of your questions:

  Client certificate or user

  http://www.Cisco.com/en/us/Partner/Tech/tk59/technologies_tech_note09186a00804b976b.shtml#T10

  Computer certificate

  http://www.Cisco.com/en/us/Partner/Tech/tk59/technologies_tech_note09186a00804b976b.shtml#T15

  In the case of EAP - TLS we have the certificate of computer and user installed on the machines.

• Install certificates for EAP - TLS does ACS does not work

  Hi all

  I have two problems.

  I produced a CSR ACS and sent my people to windows this and they published my ACS with a certificate. Cool.

  I'm going to download the GBA and I put a 'private key file?

  What is this file? and where can I get a? What is this long string of characters that generate the CSR, I sent the boys of windows?

  Also, I managed to just put any old rubbish in there? and I was surprised he accepted.

  Restarted the service IS and I tried to turn it on eap - tls on the "Overall Authentication Configuration" page to get only the message

  Could not initialize authentication PEAP or EAP - TLS because that Protocol

  certificate is not installed. Install CA using "ACS."

  «Configuration of CA page»»

  Now, I'm a little confused, because if have the installer GBA incorrectly, because of my lack of understanding of what this private key file and how it relates to all which?

  Thx a lot indeed.

  Ken

  I'm having the same problem. It seems the guys from windows to generate a cert that it must be exportable, which offers also private key file. I tried the following without success document. It can work for you, however, http://www.cisco.com/en/US/products/sw/secursw/ps5338/products_configuration_example09186a008020a45c.shtml

  I also tried to have the ACS to generate a certificate self-signed, that works. But on the client, you must uncheck the box validate the server certificate because GBA is not a trusted certificate servers. Right now I'm trying to understand how ad to publish the ACS as a trusted cert server so windows knows to do trust the cert of the ACS. Through all this, I found that you can configure in several ways, the most difficult part is to find a way that works for you.

• Authorization of EAP - TLS machine uses ACS 5.2

  Hi all

  I've been struggling with this during a few days now and I think there must be something I'm not quite understand.

  We strive to deploy new wireless infrastructure using windows, APs from Motorola (with switches RFS) wireless clients and using a Cisco ACS as Radius Server 5.2.

  Trying to get EAP - TLS to work, I can get customers to connect if no actual authorization is used, but when I try to validate if the name of the computer in the client certificate belongs to a particular group, the authorization fails.  I don't see how to get the ACS to use the RADIUS "Username" it receives via the certificate allowing the machine.  The value of the Radius user name attribute is the name of the machine.  I would like the ACS to check to determine if this computer name belongs to a group, especially in the Windows AD.

  We started with PEAP-MSCHAPv2, but security wanted machine authorization so we thought that EAP - TLS was the only way to get it.  Now I'm not sure.

  I would like if someone can guide me in obtaining the ACS to validate if the computer belongs to a group in Active Directory using

  (1) EAP - TLS

  (2) PEAP-MSCHAPv2

  Thank you!

• [ISE or ACS] EAP - TLS or profiling as the same SSID

  Hello

  I can only configure one SSID to connect 2 types of devices:

  • Devices with certificates connect on this SSID using EAP - TLS
  • Devices without the ISE profiles certificates (or ACS verifies their MAC addresses)

  Could this work?

  How can I configure this type of SSID on WLC?

  • 802. 1 X works
  • 802.1 X + MacFiltering works.
  • I failed to configure 802.1 X or MAC filtering...

  Thanks for your help,

  Patrick

  Hello Patrick.

  Unfortunately, I don't think that's currently possible in the world of wireless Cisco with a unique SSID. For your example, you will need two separate SSID. Something similar has been asked before:

• ACS 4.0 EAP - TLS Cert does not

  Hey,.

  so, I have generated my certificate signature request, took it to my CA, a cert. "ACS Certification Authority Setup" I have installed on my device ACS, then 'Install ACS certificate' installed (he parked in the privkey and password so I guess he got that comes from the cert file). I then add the CA to "change CTL. All of this goes off without a hitch.

  However when I try to add the "certificate revocation list" I am unable to add the two LDAP:------and http://. I confirmed that the http:// is working on the certification authority, and all the possible indications are that the ldap protocol works too but I can't test with tools.

  When I go to "System Configuration"-> "Global Authentication Setup"-> "allow EAP - TLS' I get the following error.

  Could not initialize the PEAP or EAP - TLS authentication protocol because the certificate authority is not installed. Install the certification authority by using the "ACS Certification Authority Setup" page.

  Exactly, which is not installed on the certificate? It is on the ACS server, it is configured and the date range is correct.

  I've been banging my head against this all day and could use some suggestions. :)

  Hello

  For EAP - TLS to work you must use external CA installation such as Microsoft or Rapid SSL etc and auto generated in ACS certificates supports PEAP support but not EAP - TLS.

• Machine based authentication using EAP - TLS, MS CA and 5.2 of the ACS

  I use ACS 4.2 for Windows for a couple of years now and I'm pretty comfortable with it.  5.2 model is much more different than what I expected.  We downloaded the trial in our laboratory for 90 days, and I try to get 802. 1 x wired works so we can be sure that we want to buy it.  I've looked everywhere and I have been unable to find some basic instructions on how to configure the following in a step by step process scenario:

  1. integrated AD

  2 EAP - TLS

  3 certificates

  4 Microsoft CA

  5. the applicant is XP SP 3

  6 non-Cisco 802.1 x compatible switches (switches are not the question)

  I got GANYMEDE to work fairly easily, but I am confident the issues I have are user based :).  Does anyone know of a doc somewhere that goes on a scenario like this (in addition to the user manual and docs of migration ISBN)?  Also, we have the assurance of software on our box 4.2 - TAC support questions we have on the 5.2 box while we are it do demonstrations?

  Thanks in advance.

  Hello, Christopher.

  I'll try to give you some tips to achieve what you want.

  Additional info can be found in the user guide:

  http://www.Cisco.com/en/us/docs/net_mgmt/cisco_secure_access_control_system/5.2/user/guide/acsuserguide.html

  1. in the identity store / Active directory, check "enable machine authentication.

  2 import a certificate for ACS

  Go to System Administration > Configuration > Local Server Certificates > Local certificates and click the Add button.

  Select how you want to import the certificate, and then verify the Protocol EAP

  3. Add your switches as aaa clients

  Access network resources > network hardware and the AAA Clients, click on create and add configure address IP + shared secret for the RADIUS.

  4-go to access policies > Access Services and click on create a new access service.

  Select the selected Type of Service and network access in the list.

  Verify the identity, group mapping and authorization

  5 - go to the access policies > rules of selection and select "Rule based selection result" if not already done, then click Customize at the bottom right of the screen, and then add the properties that allows you to match your device with which you want to do TLS.

  You can use the IP address of devices, or you can create a NDG (in network resources), assign devices to the NDG and match this NDG in your rule.

  If all your switches RADIUS will make eap - tls, you can change the rule

  Rule-1

  Ray game

  Default network access

  While in the result, you choose your service of access created in step 3.

  6 - go to the access policies and click on the access service that you created in step 3. In the allowed Protocols tab, see EAP - TLS

  7. unfold your access service menu, and then click identity. Select your ad as being the source of the identity

  8. check that the 'Allowed access' rule is selected in the authorization to access your service

  These measures define your devices, and then create a rule to say that ACS must use an individual service for this access devices and set this access service to use AD as authentication.

  Again, what are the basic steps, he may miss some things to do depending on your configuration, but I hope this will help you.

  ACS 5 may be difficult at first, but once you get your hands on it, you will see that it is powerful.

• Wrong with EAP - TLS with Wireless before Windows logon

  Evil begins with a list of equipment;

  5508 WLC

  3502i AP

  Cisco ACS 5.3

  Clients Windows 7

  WLAN is set up with WPA2 AES with 802. 1 x for key management.

  Customer is set up with WPA2/AES, authentication method is Microsoft: card chip or other certificate on the computer. Authentication mode authentication is the user or computer.  The client is configured to use a certificate on the computer.  "It only works if the authenticating user or computer is seected."  If I use computer authenticate option... it says that it cannot find a certificate to use for the EAP.

  ACS is configured to allow only for the EAP - TLS protocol.

  We have created a stand-alone CA server and distributed CA certificates root and client authentication for all test systems.

  This whole process with EAP - TLS works very well if you are already connected to the machine, with the credentials of the cache.  Once I disconnect the Windows 7 client, I lose the connection to the WLAN.  We want to stay connected to the WIFI network.  W PEAP / MSCHAPV2 works very well with stay connected to the WLAN, but we want to use EAP - TLS.

  Any ideas?

  Thanks in advance,

  Ryan

  Hi Ryan,

  You actually answer your own question :) The reason for the fault is because the computer account doesn't have a certificate, so when your computer account user cannot connect to maintain the session going, and so you are disconnected. Provide the computer with a certificate account and your problem will be solved.

• PEAP EAP/TLS, PORTEGE with WinXP sp2 Tablet Edition problem

  We have: Rev AiroNet350 Cisco with WPA - EAP: Freeradius with EAP/TLS and PEAP, tablet PC PORTEGE with WinXP sp2 configuration.

  This problem discribed in http://wiki.freeradius.org/index.php/FAQ#PEAP_Doesn.27t_Work
  Perhaps to solve this problem we need a fix (http://support.microsoft.com/kb/885453/en-us), but microsoft support said to contact the laptop manufacturer.
  Can someone help me with this problem?

  Hmmm I m not an expert in this area, but it seems that the MS OS update is necessary. (I hope)
  The preinstalled Windows operating system is a simple OEM version and generally all updates should be possible. However, if MS guys told you to communicate with the manufacture of the laptop, you can contact the maintainer authorized Toshiba in your country for details.

  But I studied a bit on the net and found this site useful:

  1. 802. 1 X is based on communication between your router and a RADIUS authentication server. If you use WEP, WPA or WPA2 with dynamic keys, 802. 1 X debugging following tips may be useful:
  a. reintroduce the same RADIUS secret in your wireless router and the RADIUS server.
  b. configure your RADIUS server to accept the request of the RADIUS of the IP address of your router.
  c. use ping to check the accessibility of router-server.
  d. package watch LAN account to verify that RADIUS and answers queries are fluid.
  e. use an Analyzer like Ethereal Ethernet to watch RADIUS success/failure messages.
  f. for XP SP2, turn on Wzctrace.log by typing "command netsh ras set followed * activated.

  2 if RADIUS is flowing but are rejected requests for access, you may have a problem of incompatibility or credential X Extensible Authentication Protocol (EAP) 802.1. This setting depends on Type EAP. For example, if your RADIUS server requires EAP - TLS, then select 'Card chip or other certificate' of your adapter wireless network properties / authentication Panel. If your RADIUS server requires PEAP, then select "Protected EAP" of the adapter. If your RADIUS server requires EAP-TTLS, then you will need a third-party wireless like AEGIS or in Odyssey client.
  Make sure that this specific EAP properties match for your adapter and the server, including the server CA certificate root trust Server domain name (optional but must match when it is specified) and the customer (EAP-MSCHAPv2, EAP - GTC) authentication method. When you use PEAP, use the control panel to 'Configure' CHAP to prevent Windows from automatically re-use of your connection.
